分析现有行星轮系机构,提出一种新型的基于偏心圆-不完全非圆齿轮间歇传动行星轮系机构,在一个工作周期内,实现行星轮相对行星架作非匀速间歇转动.介绍该机构的工作原理和运动学特性,建立行星轮系机构模型.开发该行星轮系机构的计算机辅助分析软件,通过人机交互方式得出一组满足非匀速间歇传动的结构参数.基于该参数对该行星轮系机构进行设计及试验,并将该行星轮系机构成功应用于穴盘苗取苗机构的创新设计,并进行取苗试验,从而验证了该行星轮系机构理论模型的正确性和可行性.
Research on a New Planetary Gear Train Mechanism
A new intermittent drive transfer mechanism of planetary gear train with eccentric circle and incomplete non-circular gear is designed on the basis of the analysis of recent advances.In one work period,non-uniform intermittent rotation of planet gear relative to planet carrier is achieved.Work principle and structural feature of the mechanism are introduced,kinematics model is established.The software of computer-aided analysis for this intermittent drive transfer mechanism of planetary gear train is developed.By human-computer conversation,structural parameters are carried out,which can meet the demand of driving.Based on these parameters,design and test of this intermittent drive transfer mechanism of planetary gear train are carried out.The mechanism has been successfully used in creation design of vegetable plug seedling pick-up mechanism,and experimented with transplanting seedling.The correct and feasible of theoretical model of planetary gear train mechanism are verified.
